thanks speedy! yeah i guess it would be just a little heavier!
I know that the 94 3100 was rated close to 160 Hp and the later roller rocker (96+)heads added like 10Hp but I would hope that the higher Tq rating would help accelerate the car!
Regardless I am still working on getting the 90 bonnieville, I am still pretty sure I can "ofer" to junk the car for him LOL
we shall see.....[maniacle laugh/]
